Lucid switched to plasma-widget-networkmanagement, so use plasmoid to control network interfaces. Only one of this frontend can be used at one time and default is noww plasmoid.

If you do not want to use plasmoid, you have to stop KDED Networkmanagement module and restart knetworkmanager.

It seems that for unknown reason in:
/var/lib/NetworkManager/NetworkManager.state
[main]
NetworkingEnabled=false
WirelessEnabled=true
WWANEnabled=true

Just changing to
NetworkingEnabled=true

solves the problem after restart

I got this again today after the computer was improperly shut down.
